AUTOMATED PRESENCE DETECTION AND PRESENCE-RELATED CONTROL WITHIN AN INTELLIGENT CONTROLLER
First Claim
1. An intelligent controller comprising:
- a processor;
a current control schedule stored in the memory;
one or more sensors;
a memory that stores a control schedule and an indication of a presence state; and
instructions stored within the memory that, when executed by the processor, controls the intelligent controller torecord output from the one or more sensors in memory; and
at intervals,determine a probability of presence of one or more types of entities within a region of a controlled environment using the recorded sensor output in memory,update the indication of the presence state, andupon a change of the indication of the presence state, accordingly adjust the control schedule.

Abstract
The current application is directed to intelligent controllers that use sensor output and electronically stored information, including one or more of electronically stored rules, parameters, and instructions, to determine whether or not one or more types of entities are present within an area, volume, or environment monitored by the intelligent controllers. The intelligent controllers select operational modes and modify control schedules with respect to the presence and absence of the one or more entities. The intelligent controllers employ feedback information to continuously adjust the electronically stored parameters and rules in order to minimize the number of incorrect inferences with respect to the presence or absence of the one or more entities and in order to maximize the efficiency by which various types of systems controlled by the intelligent controllers carry out selected operational modes.

12. An intelligent thermostat comprising:
-
a processor; a current control schedule stored in the memory; one or more sensors; a schedule interface; an immediate-control interface; a memory that stores a control schedule and an indication of a presence state; and instructions stored within the memory that, when executed by the processor, controls the intelligent thermostat to record output from the one or more sensors in memory; and at intervals, determine a probability of presence of one or more people within a region of a controlled environment using the recorded sensor output in memory, update the indication of the presence state, and upon a change of the indication of the presence state, accordingly adjust the control schedule. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method, incorporated within an intelligent thermostat comprising a processor, a current control schedule stored in the memory, one or more sensors, a schedule interface, an immediate-control interface, and a memory that stores a control schedule and an indication of a presence state, the method comprising:
-
recording output from the one or more sensors in memory; and at intervals, determining a probability of presence of one or more people within a region of a controlled environment using the recorded sensor output stored in memory, updating the indication of the presence state, and upon a change of the indication of the presence state, accordingly adjusting the control schedule. - View Dependent Claims (20)
